Use the New Mailbox wizard to create a new mailbox in your Microsoft Exchange Server 2007 organization. An Exchange 2007 mailbox is a combination of an Active Directory directory service user object that has mailbox attributes and the associated mailbox data that is stored in the mailbox database. You can use the new mailbox for a user or for resources such as meeting rooms and equipment.

Note:

You can also use the Exchange Management Shell to create a new mailbox. For more information, see New-Mailbox (RTM).

Use this page to specify the mailbox type. Select one of the following types.

User Mailbox

Click this button to create a mailbox that is owned by a user to send and receive e-mail messages. User mailboxes cannot be used for resource scheduling.

The Active Directory account that is associated with user mailboxes must reside in the same forest as the Exchange server. To use an account in a trusted forest, select Linked Mailbox.

Room Mailbox

Click this button to create a mailbox that will be used as a location resource for scheduling meetings. Room mailboxes can be included in meeting requests as resources and can be configured to automatically process incoming requests.

If you create a new user account for the room mailbox in Active Directory, it will be disabled. If you plan to associate the new room mailbox with an existing account, you must select a disabled account.

Equipment Mailbox

Click this button to create a mailbox that will be used as a resource for scheduling meetings. Equipment mailboxes can be included in meeting requests as resources and can be configured to automatically process incoming requests.

As a best practice, create mailboxes for shared meeting equipment, such as projectors or audio equipment, which can be moved to different meeting rooms.

If you create a new user account for the equipment mailbox in Active Directory, it will be disabled. If you plan to associate the new equipment mailbox with an existing account, you must select a disabled account.

Linked Mailbox

Click this button to create a user mailbox that is accessed by a user in a separate, trusted forest. You must still create a user account in the forest in which Exchange Server resides. This is required to create the necessary Active Directory object for storing the mailbox information.

Linked mailboxes may be necessary for organizations that choose to deploy Exchange in a resource forest. The resource forest scenario allows an organization to centralize Exchange in a single forest, while allowing access to the Exchange organization with user accounts in one or more trusted forests.
